webertherm insulation options

Which external insulation board material is specified in your EWI system will be based on a number of factors including the cost, thermal performance levels required, space available and the construction type. The following rigid insulation board options are available for use as part of our webertherm external wall insulation systems for solid wall insulation:

webertherm EPS — expanded polystyrene insulation using polystyrene insulation sheets as part of a Weber external wall insulation system

webertherm EPS

webertherm EPS is the most popular product used in external wall insulation. It is a cost effective yet durable product and is lightweight, non-toxic, and is completely recyclable. It is easy to install and will perform for the lifetime of the building.

The expanded polystyrene insulation board has fantastic thermal properties with a thermal conductivity lambda value of 0.030 W/mK

  • Available in a standard 1200x600mm size and in a range of 20-200mm thicknesses
  • Forms part of a BBA and NSAI Certified Systems
  • The webertherm EPS  polystyrene wall insulation board is supplied as Reaction to Fire Class E, containing a flame-retardant additive

webertherm PHS Board — exterior insulation board for use with exterior insulation systems from Weber UK

webertherm PHS

webertherm PHS is a more expensive form of external solid wall insulation but the thermal properties of the PHS board are very high – so you can achieve the same thermal properties with much thinner material, which may be crucial for some projects.

The phenolic board has exceptional thermal properties with a thermal conductivity lambda value of between 0.020 W/m K and 0.023 W/m K depending on the insulation thickness.

  • Available in a standard 1200x600mm size and in a range of 20-70mm thicknesses, other sizes available on demand
  • Forms part of a BBA and NSAI Certified Systems
  • webertherm PHS achieves Class 0 Rating, as defined by Approved Document B in England and Wales, and Technical Booklet E in Northern Ireland. It also achieves medium risk, as defined in the Technical Handbook in Scotland.

webertherm MFD Board — rockwool insulation is a mineral wool insulation for use with Weber external insulation systems

webertherm MFD

webertherm MFD thermal properties are similar to EPS, but is slightly more expensive to install. It does however have additional benefits. Mineral wool insulation is non-combustible and is also good at absorbing acoustics where noise pollution may be an issue.

The mineral fibre thermal insulation board has a thermal conductivity lambda value of 0.035 W/m K.

  • Available in a standard 1200x600mm size and in a range of 30-200mm thicknesses
  • Forms part of a BBA and NSAI Certified Systems
  • webertherm MFD achieves the highest Euroclass Fire Rating of A1 which negates the need to install fire barriers

Other types of external wall insulation boards

Other thermal insulation materials are available dependant on the requirement and specification. Exterior wall insulation suitable for fire breaks and below DPC are available, please contact the Weber technical department or your local Weber representative for more information.
